Given numbers are 421,421,503,560
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 421,421,503,560 is 118587280.
Find LCM of 421,421,503,560 with Prime Factorization
421 | 421, 421, 503, 560 |
1, 1, 503, 560 |
Multiply the prime numbers at the bottom and the left side.
421 x 1 x 1 x 503 x 560 = 118587280
Therefore, the lowest common multiple of 421,421,503,560 is 118587280.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
421 x 421 x 503 x 560 = 49925244880
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
421 : 1, 421
421 : 1, 421
503 : 1, 503
560 : 1, 2, 4, 5, 7, 8, 10, 14, 16, 20, 28, 35, 40, 56, 70, 80, 112, 140, 280, 560
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 421,421,503,560, is 1.
Now, the common factors can be found like this.
421:421
421:421
503:503
560:2x 2x 2x 2x 5x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
421 = 421
Therefore, the value for common factors is 421.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 49925244880/(1x421)
LCM = 49925244880/421
LCM = 118587280
Thus, we can understand that the LCM of 421,421,503,560 is 118587280.
